Durable Concrete Repairs on High Profile Projects

Description 

The presentation will provide an overview of details for creating durable concrete repairs in high profile case study projects, with a focus on below grade leak prevention. It is important to understand characteristics of the repair material properties as well as the substrate material. Chemical grouts are one repair solution for stopping leakage in concrete structures. Not all grouts are the same, therefore this presentation will discuss advantages of selecting a grout or combination of grouts to provide the most successful repair solution. 

Experience and industry knowledge – both past and present – creates the foundation of designing “durable” lasting repairs. The presentation will illustrate examples of materials charts and a sample of a project “check list.” This information has proved to be critical when evaluating how to mitigate or manage leakage, especially when faced with an “emergency” project. These tools become a valuable asset when there is no existing history of products used on previous repairs.  

The presentation will contain pictures and background covering high profile leak repair projects starting in 1997 and continuing through 2025. These case histories include: Boston’s Central Artery Big Dig Tunnel, Humboldt Bay Nuclear Power Plant, 2001 – 9/11 World Trade Center emergency repair and subsequent Freedom Tower repairs through 2011, Puerto Rico Combined Cycle Power Plant – below sea level uplift pier repairs, United States Government Publishing Office 2017, 2023 and 2025, and Hartford, Connecticut Combined Sewer Outflow TBM Tunnel. The presentation will conclude with a reference to ICRI guidelines, webinars, and field reports.
